Depends on the person I think, but I have had working birds and such and when they are WORKING animals they have no place as a pet IMO for someone else, I used to cull birds from my flock, and the majority were killed, because they are of no use to me for the purpose I need them, and I had no one who would want my scrap, no good birds. Its like giving away a jacked up animal lol Now I have also hung out with many old bird men, who had scrap no good birds and would gladly give them to me because his scraps are much better than the birds most people can get easily out here, and you can sometimes get good stock off of a scrap bird.. but thats birds lol I cull them because I dont want anyone to use them for something stupid, and its just easier than worrying about what to do with the extra birds that dont make the cut. I know its still very common in the birds..
